Rehanna is a feminine given name of Arabic origin, a variant of Rayḥāna derived from the noun rayḥān, “sweet basil” or “fragrant herb.” In English it is pronounced rih-HAN-uh (/ɹɪˈhænə/) and carries associations that range from early Islamic history—where Rayhana bint Zayd is remembered as a companion of Muhammad—to contemporary culture, notably through admiration for the singer Rihanna. In the United States, Rehanna has maintained a low but steady presence in Social Security Administration records since the late 1970s, registering annual occurrences in the single to low-double digits and ranking between roughly 770 and 980. Its modest popularity suggests that parents seeking a name with historical depth and modern resonance will find Rehanna a distinctive choice unlikely to multiply on the kindergarten roster.
